Question

the area of trapezium is 360m² , the distance between two parallel sides is 20 m and one of parallel side is 25m. find the other parallel side​

Answer 1

Step-by-step explanation:

let the other parallel side be x

area of trapezium is = 1/2 × sum of parallel sides × height

360 = 1/2×25+x×20

360×20=25+x

36=25+x

36-25=x

11=x

hence the other parallel side is 11

hope this is helpful for you ❤️❤️

Answer 2

Area of a trapezium =360m²

Distance between two parallel sides =20m

one of parallel side=25m

Area of a trapezium=½×distance between two parallel sides ×sum of parallel sides

Let the other parallel side be 'x'

According to the question=>½×20×(25+x)=360m²

=>10×(25+x)=360m²

=>(25+x)=360÷10

=>(25+x)=36

=>x=36-25

=>x=11m

Therefore, the other parallel side is 11m.

hope it will help you.
